Could it be as simple as the second option in
https://bugs.freedesktop.org/show_bug.cgi?id=94508#c11 ,
namely arrange for system-config-printer-applet to connect to the X display
so that it gets killed when the X session exits? Maybe that can be done
without the full overhead of inserting an icon into the notification area,
which I understand the applet deliberately avoids doing until a job has been
printed?
